Favorite Architectural building

My favorite architectural piece in NYC so for is the building of the freedom towers and the memorial. Although it is not finish, the finish product of the project, as well as the current progress of the building amazes me when I have time to look at it in person as well as looking at images of it. When the buildings are done, they are making it so that at a certain time in the morning, the sun shines over the buildings, casting a shadow of the buildings over the memorial. The shadow is supposed to represent the twin towers. I really admire that the architect who designed this structure put a lot of time and effort into this. When it is finally finished, I know it will attract a lot of visitors.
